Hey guys this is one of the cheapest mods i did and might even gain some power. I wanted to add some cooler air to my bbk open air filter intake,soo the other day i went to my lowes and bought some Flexible aluminum air condition ducting for 10.95 and some 24in zipties.The air comes throug the drivers side corner of the zl1 lower grill (this is where the brake cooling ducting would be on a actuall zl1) And bent the pipe to let the air out right on the open filter. Here are some pics if anyone has any questions post them up!
